I enrolled my 6 yr son for summer. They made math so fun that he loves going to Mathnasium. They teach different techniques and they encourage him to solve using multiple ways. They keep it interesting by teaching on his favorite animal pictures and by giving small rewards. There are math games and board games, so he plays with his friends after the class is over. They provide individual attention to each student.

Mathnasium is great. The center director is awesome to work with to schedule appointments and accommodate specific aspects of learning. We are also pleased with the other instructors who teach the kids. My kiddo likes it overall and loves the puzzles that they do at the end everyday. I think making Math fun to kids is the key and they do it great.

My child loved her summer camp so much she did not want to leave at the end of each class. She wanted to go every day she said. I will definitely sign her up for more camps. She already excels at math, so this showed her it can be fun as well as teaching her new concepts.

Special Mention about Ms.Heather- She is very open in communicating and incorporates parental feedback right away! Within just a month into classes, I see my daughter's confidence has increased in approaching a "seemingly difficult" question. She is not very averse to numbers and mental math like she used to be.

The private tutoring provided by Mathnasium in Round Rock has really helped my daughter better understand Algebra. She was struggling with math and needed additional help to prepare for the Staar test. She feels comfortable asking questions and she feels it is helping her.

Mathnasium was able to provide the foundation for my son to be successful in math. He was able not only able to catch up to his peers but to surpass their skills and is now in accellarated math.
I highly recommend Mathnasium.

My son Rayyan [LAST NAME REMOVED] was supposed to take CBE for grade 8.

When our daughter started failing math we knew we had to do something. We heard about Mathnasium and decided to give it a try. It only took a few months the to see a difference in her grades. She went from failing to an A in about a year. We are extremely happy with our results and our daughter has more confidence in mathematics.

Heather was always very helpful in setting up appointments and David was very instrumental in my Son Austin Stiglets passing Pre Cal..Thank you very much and congratulations on having the two above mentioned on your staff.

I am extremely please with the positive change Mathnasium has been for my son. His math skills have improved by leaps and bounds. He is no longer afraid of math and welcomes the challenge to learn more. Thank you Mathnasium Staff!

My son has grown so much, he has become more confident in math. He doesn't seem as stressed as he did a few months ago. The staff is friendly and helpful. When he needs additional assistance, he is not affraid to ask and they do a great job at explaining not just one method, but several. They determine his learning method and adjust or redirect his method used to ensure he is learning. I am very satisfied with his improvements.

My son needed help with Pre-AP Pre--Cal and the tutors and Heather were wonderful to work with. My son is making a B in class now, instead of a C. We do appreciate the help and flexibility of the scheduling. Any time we call, we are able to get him in for tutoring within a day or two. Thank you!!

Mathnasium works great for both my kids in that we take time out specifically to do math and they get clarifications on any sum or problem they get stuck on right away. The schedule is very accommodating and flexible which helps a lot when there is a clash with other activities. When kids understand math it also becomes fun and easy to practice which then reflects in their grades. The results are long term and not visible overnight.

Has helped tremendously with my daughters confidence in her Math skills. I appreciate how Mathnasium communicates to my daughters teacher things that's she is improving on and things she still needs assistance with.

Ben spent almost a year at Mathnasium and his transformation was amazing. He went from a C to an A in Math but also improved grades in his other subjects. Mathnasium didn't just help him with math - it built up his confidence and helped him do better in school. He is in 6th grade now and has carried an A in math all semester.

I love the friendly atmosphere and how comfortable Levi is. He is getting more confident in math and independent. I also love that you send updates,talk to the teacher and that there isn't extra homework to do.

My kids love coming to Mathnasium and it has made a huge impact on their math grades. My daughter didn't have an interest in math initially and thought she wasn't any good at it, but Mathnasium has bolstered her confidence and she is now a really great math student. She is showing a distinct interest in math and science and we believe that is in large part thanks to her involvement with Mathnasium.

We love Ms. Heather and appreciate that she works with our busy schedule. We like that when our daughter does well, Ms. Heather and her team share our daughter's joy. The same can be said if our daughter doesn't do well the team feels her pain and works hard to help her prepare for future exams. Our daughter also enjoys working with Jorge & Mark. I've recommended mathnasium to several friends.
